As a proof of concept I could come up with a printer for reverse_iterator that
works on lists. Not very elegant, and this would need to be implemented for all
the other containers, too (because we cannot use operator-- when debugging a
core dump).
Don't know if it's worth the hassle, but as a starting point, here it is:
class reverseprinter(object):
"print a reverse_iterator. works only for list"
def __init__(self, typname, val):
self._val = val
def to_string(self):
# save the type of iterator, so we can use its prettyprinter
current_type = self._val['current'].type
# this works for list only:
return self._val['current']['_M_node']['_M_prev'].cast(current_type)
def display_hint(self):
return 'string'
and in register_libstdcxx_printers add:
libstdcxx_printer.add_container('std::', 'reverse_iterator',
reverseprinter)
